A removable filter assembly for filtering a fluid having a particulate or a contaminant and configured to engage a filter housing having a center post. The removable filter assembly includes a filter element adapted to remove at least one of the particulate or contaminate from the fluid, wherein the filter element includes an interior wall defining a passage having a first end and a second end. A container arrangement includes a channel and an outer wall in contact with the filter element at the first end of the passage, wherein the outer wall defines an outer profile extending from the first end of the passage toward the second end of the passage. The channel defines an inner wall configured to provide a relatively fluid tight seal with the center post. The container arrangement is adapted to capture at least one of the particulate or contaminate from the fluid. The outer wall of the container arrangement can include a plurality of radially aligned ribs.
1. A removable filter assembly for filtering a fluid having a particulate or a contaminant and configured to engage a filter housing having a center post, the removable filter assembly comprising:
a filter element adapted to remove at least one of the particulate or contaminate from the fluid, wherein the filter element includes an interior wall defining a passage having a first end and a second end; and
a container arrangement including a channel and a non-porous outer wall in contact with the filter element at the first end of the passage; the container arrangement adapted to capture at least one of the particulate or contaminate from the fluid;
